[...] being human is being a young child on Christmas Day who receives and absolutely magnificent castle. And there is a perfect photograph of this castle on the box and you want more than anything to play with the castle and the knights and the princesses because it looks like such a perfect human world, but the only problem is that the castle isn't built. It's in tiny intricate pieces, and although there's a book of instructions you don't understand it. And nor can your parents or Aunt Sylvie. So you are just left, crying at the ideal castle on the box which no one would ever be able to build.
I wonder if I've been changed in the night? Let me think. Was I the same when I got up this morning? I almost think I can remember feeling a little different. But if I'm not the same, the next question is 'Who in the world am I?' Ah, that's the great puzzle!
Before you, Bella, my life was like a moonless night. Very dark, but there were stars – points of light and reason. And then you shot across my sky like a meteor. Suddenly everything was on fire; there was brilliancy, there was beauty. When you were gone, when the meteor had fallen over the horizon, everything went black. Nothing had changed, but my eyes were blinded by the light. I couldn't see the stars anymore. And there was no more reason for anything.
"There is a room in the Department of Mysteries," interrupted Dumbledore, "that is kept locked at all times. It contains a force that is at once more wonderful and more terrible than death, than human intelligence, than forces of nature. It is also, perhaps, the most mysterious of the many subjects for study that reside there. It is the power held within that room that you possess in such quantities and which Voldemort has not at all. That power took you to save Sirius tonight. That power also saved you from possession by Voldemort, because he could not bear to reside in a body so full of the force he detests. In the end, it mattered not that you could not close your mind. It was your heart that saved you."
You think the dead we loved ever truly leave us? You think we don’t recall them more clearly than ever in times of great trouble? Your father is alive in you, Harry, and shows himself plainly when you have need of him. How else could you produce that particular Patronus? Prongs rode again last night.
